The LCD-3s are my current favourites but basically I have not had the luxury of even trying the 009s yet (and for my wallets protection, I should make sure I don't do!)
But I have to say that I really do not like the HD800s. Try putting them on a digital electronic piano like a Yamaha Clavinova and they give a very unrealistic timbre rendition of a piano. The LCD-3s (and 2.2s as well) give a very very good piano timbre reproduction.
With music as well I always feel with the HD800s that someone turned the treble up too high.
I know people love this headphone and I am only posting to illustrate that if there were such clear answers, we would all choose the same one. The fact is this is very personal. I have extremely fine tuned and receptive high pitched hearing. I find it almost hurts my ears if the treble is too much. That's not to say I like a muddied warm sound either. I need good treble in my daily life..I find it very hard to hear people on conference calls if they use a speaker phone and the treble is all gone, whereas my colleagues have no such issue. I need good clear treble, but I absolutely detest over-blown treble. To my ears, and probably my ears only, the HD800s sound way too bright.
